More from Sigma in 2013
We’re told Sigma will announce a 135mm f/1.8 DG OS Art lens sometime in 2013. There could be up to 3 more Art lenses announced this year. We’ve previously heard they would be releasing a 24mm f/1.4 DG Art sometime in 2013.

There has been no mention of an f/2 or faster zoom for full frame cameras.

Wow Sigma are on a farkin mission eh? I hope we see the updated 50 sometime soon, I could use it. I'll stick with my 135L, that thing is sharp enough and fast enough though I will be watching the reviews closely!
